The Irish Aviation Authority (IAA) revealed the information yesterday, and confirmed that the disruption was caused because two Russian bombers flew through Irish-controlled airspace, without warning, 25 nautical miles (28.7 miles) off the coast of Ireland. They also had their identifying transponders switched off.

The IAA did confirm that ,despite one plane being diverted to avoid the bombers, there was "no safety impact to civilian traffic in Irish controlled airspace".
